I like this park in the summer time for obvious reasons: it has three baseball diamonds, a skateboard area, a small playground and a community pool.
As the cooler months settle in, Alexandra Park loses its charm a bit and most of these perks are rendered useless. It's not super well lit at night so you may need to cut your playtime or walk short in the fall or bring a flashlight.
There is also lots of questionable groups of people who hang out at this park, so don't be surprised if you see police trolling around the area and arresting said folks!
